SPECIFICATION forming part of Letters Patent No. 761,958, dated June 1904. Application filed November 13, 1902. Serial No. 131,259- (No model.)

To all whom, it nuty concern:

Be it known that I, FRED C. HAAR, a citiien of the United States, residing at Gibsonburg, in the county of Sandusky and State of Ohio, have invented certain new and useful Improvements in VVell-Drilling Machines; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and

to the figures of reference marked thereon, which form a part of this specification.

My invention relates to improvements in well-drilling machines; and the primary object is to provide mechanism whereby the drillrope and sand-rope may be effectually handledl In drilling wells it is of the utmost importance that the mechanism for manipulating the tools be arranged in such manner that the operator may readily regulate the adjustment of the drill-rope to obtain the best results-or to quickly withdraw it. Then, again, it is highly important that the sand rope may be controlled .in such manner that the sand-bailer may be raised or lowered quickly; otherwise expense is added to the cost of the digging, as

well as delay in completing the operation. I overcome these undesirable features by arranging on a frame an engine "as a source of power to communicate motion through appropriate gearing to a drill-rope drum and a sandrope drum, the motion of both drums being controlled by suitable levers. rangement of gears and levers I am enabled to impart motion direct from a power-shaft to the spudding-beams which jigs the drill rope, pay out the drill-rope or wind it at will, and wind and unwind the sand-rope, these various operations being brought about through the intervention of a single power-shaft.

The invention further relates to improvements in the particular arrangement of folding the frame for storage and transportation, likewise the specific means employed whereby the main beam may be disconnected and. a walking-beam substituted therefor, the walking-beam carrying the usual temper screw or clamp.

By this ar Many other objects and advantages will be hereinafter referred to in the description and be particularly pointed out in the claims.

In the drawings, Figure 1 is a side-elevation At the forward end of the sills 2 are a pair of standards 4, pivoted to said sills and rendered adjustable and locked through the medium of bolts 5. Pivotally mounted to the upper ends of the standards tie a derrick-frame comprising a pair of side uprights 6 and cross-bars 7 (only the ends of the latter being shown in Figs. 1 and 2,) braced by supportsfi, fastened to the uprights and the frame 1. Bolts 8 are used to fasten the uprights to the standards I when the apparatus is in operation and when out of use the bolts are withdrawn,whereupon the uprights are turned down and their opposite ends rest on a bar of asupplemental frame 9, secured to the main frame 1. To further brace the uprights when drilling, wedges 6 are driven under the ends of the derrick.

10 represents a power-shaft mounted in bearings in the frame 1, and made fast to one end of it is a band-pulley l1 and has at the opposite end a friction-gear 12. Intermediate the side sills 3 the shaft 10 carries a second but smaller friction pinion 13 and a slidablymounted pinion 14, bearing a grooved hub 15.

A lever 16 is pivoted at 17 and its forked end engages the grooved hub 15, while its opposite end is connected to a hand-lever 18, adapted to slide back and forth in guides.

- On a bar 20 and one of the sills 2 is mounted a shaft 21, bearing'a bull or gear wheel 22, adapted to mesh with the pinion 14. when the latter is slid into engagement therewith by opcrating the lever 18. On the inner endof the shaft 21 is a crank 23, connected by a pitman 24 with the spudding-beam 25, the latter being pivoted at 26 on the supplemental frame 9. A pulley 27 is mounted in a slot in the beam 25 at the pivotal point of the latter, and at the opposite end of the beam is mounted a second pulley 28.

Mounted in bearings on the frame 1 is a shaft 29, carrying a friction-gear 30, which is disposed in alinement with the friction-pinion on shaft 10. The shaft is eccentrically mounted in bearings 29 and is adapted to be moved by an arm 29 projecting therefrom, which is connected by a link 29 with one arm of a hand-lever 29. the latter being held in a locked position by the usual latch and segment. The bearings are supported in chairs 29 and are adjusted to compensate for wear by set-screws 29 On the shaft 29 is a drum 31 for the drill-rope 23. Rope 32 passes from the drum around pulleys 27 and 28, thence up and around the pulley 39 at the upper end of the derrick. The lower end of the rope carries the usual d rilling-tool LO.

By pressing down on the hand-lever 29 the friction-gear 30 is brought into contact with the friction-pinion 13 and the drill-rope is wound up. On the other hand by reversing the movement of the hand-lever the frictiongear impinges a stationary brake-block and the drill-rope and drill are maintained at any predetermined position.

A shaft 41 is mounted in bearings on the under side of frame 1, and it carries a frictionpinion 4C2 on one end and a sand-rope drum 43. The shaft is mounted in bearings substantially like those of the drill-rope shaft, and a detail description thereof is thought to be unnecessary. An arm 43 extends up from the shaft 41 and is connected by a link 44: with a hand-lever 45, pivoted at 4:6 and locked by a latch and segment 47. hen the hand-lever L5 is moved in one direction, the friction-pulley 42 engages the friction-gear 12 and the same ropeis wound up, whereas if the lever is moved in the opposite direction it engages a stationary brake-block 4C9, whereby the rope and bailer are held under perfect control.

A walking-beam 51 may be actuated by the pitman 24: in place of the spudding-beam 25. The walking-beam is pivoted to the derrick at 52 and is provided on the outer end with a head 53, braced by a support 54. The outer face of the head is concentric, the curve being struck from the pivot on which the beam rocks. Secured to the top of the head 53 is a chain 55, carrying the usual temper screw or clamp 56. The temper screw or clamp may be of any well known construction and is adapted to be used in the ordinary manner.

An engine and boiler are located on the frame 1. The valve controlling the same has a pulley 61 on its stem, and around it and a similar pulley 62, located on the derrick at the opposite end of the apparatus, passes a rope 63, by means of which the operator manipulates the valve from a point where he stands to control the lovers before mentioned.

The apparatus is mounted upon wheels for usual draft purposes.

In drilling a well the apparatus is positioned, and a platform 76 is arranged near the derrick, from which the operator has full control of the engine and the various levers and at the same time be in position to note. the progress and condition of the drilling. The apparatus having been located the operator pulls the rope 6 to turn the valve to start the engine, which through the belt 77, passing around the pulleys 78 and 11, imparts rotary motion to the power-shaft 10, which is constantly revolved. For spudding the lever 29 has been previously operated to release the friction-gear from its brake-block to drop the tool, whereupon the lever is again operated to lock the pulley against the block, the pitman is connected to the spudd ing-beam, and the rope 32 is guided from the drum 31 over the pulleys 27, 2S, and 39. The operator now pushes in the hand-lever 18 to effect engagement of the gear and pinion 14: and 22, which imparts up-and-down motion to the beam 25, and hence the rope 32. Should it be desired to substitute the walking-beam 51 in place of the spudding-beam, the latter is disconnected and the beam 51 is supported as hereinbefore described; but in positioning the walking-bemn the derrick is slightly tilted, as shown in Fig. 5, that the proper leverage maybe maintained and at the sametime bring the head 51 over the well. Going back to the spudding operation, should the operator desire to lift the tool from the well the lever 29 is thrown to engage the friction-gear 30 and pinion 13, which winds the rope 32, and consequently witlnlraws the tool.

To use the bailer, theimplement is attached to the sand-rope in the usual manner, and the hand-lever 4:5 is operated to disengage the friction-pinion 42 from the brake-block l5), and the rope unwinds and the operation is effected. To lift the bailer, thclever -15 is manipulated to cause the friction-gears l2 and 42 to engage and the rope is wound upon the drum, and when sufiicicntly wound the lever is reversed and the pinion a2 impinges the. block 49 and the drum is locked against rotation.

Of course it will be understood that inasmuch as the operator is in convenient reach of the controlling-levers the spinlding-lever is thrown out of operation at will during the operation of bailing or the raising or lowering of the drill-rope. It will be seen, therefore, that my invention possesses decided advantages over the present structures in use, inasmuch as the arrangement of the parts is such that the operator standing in one place lOO can control the movement of the rope or the speed of the engine, and yet observe the progress'of the drillin I am aware the broad principle of such arrangement of parts is notnew with me; but the specific details of construction for accomplishing the desired ends are, so far as I am aware, new.

The adjustment and folding of the derrick renders the apparatus extremely desirable over others of like type, for the reason that simplicity of structure as well as durability are combined.

What I claim as new is' 1. In a well-drilling machine, the combination with a frame, of an engine mounted thereon; a shaft 10 hearing a friction-pulley 12, a spur-gear 14 of smaller diameter than the pulley 12, a second friction-pulley 13 smaller in diameter than the pulley 12 and gear 14, and

- a band-wheel 11; means connecting the engine and the band-wheel; levers for sliding the spur-gear 14 on said shaft 10; a shaft 29 mounted adjacent the shaft 10, eccentricallyarranged hearings in which said shaft 29 is mounted, a drill-rope drum 31 mounted on shaft 29, a friction-wheel 30 on the shaft 29 which is opposite the friction-pulley 13 and larger in diameter than said pulley 13, pulley 12, and spur-gear 14; levers for operating the eccentric bearings to engage the frictionwheel 30 and the friction-pulley 13; a brake shoe positioned opposite the wheel 30; a shaft 41 mounted under the frame, a bailer-drum carried by the shaft 41, a friction-pulley 42 on said shaft, opposite the friction-pulley 12, a brake-block adjacent the friction-pulley 42; levers for operating the said eccentric bearing to cause the pulley 42 and pulley 12 to engage or the pulley 42 to contact with the.

- brake-block; a shaft 21 mounted on the frame adjacent shaft 10, a bull-wheel on shaft 21, adapted to be engaged by the spur-pinion 14, a crank connected to the shaft, a link connected to the crank; a s'puddingbeam 25 pivoted to the frame, the link being connected to the s'pudding-beam, guide-rollers carried by the spudding-beam to guide the drill-rope, and a folding derrick pivoted to the frame and carrying a roller to guide the drill-rope, substantially as described.
